A family is mourning the loss of an army veteran after he was killed by a 9-year-old during a shooting session at a gun range in Arizonaon Monday.

According to ABC News, Charles Vacca, 39, was teaching the young girl how to shoot an Uzi. After firing off a few shots with ease, Vacca’s last words were “Alright, full auto” before the girl lost control of the gun, shooting Vacca in the head.

The shooting happened at 10 a.m. Monday at Arizona Last Stop, a tourist spot southeast of Las Vegas.

According to the Mohave County Sheriff’s Office, the instructor –- identified as Charles Vacca, 39 –- was standing next to the girl, teaching her how to use an automatic Uzi. The girl’s parents stood nearby, capturing video of the experience.

As the girl pulled the trigger, the recoil caused her to lose control of the gun, with Vacca accidentally shot in the head, the Mohave County Sheriff’s Office said. Vacca was flown to the University Medical Center, where he was pronounced dead, authorities said.

The child hasn’t been identified because of her age. The range named Bullets and Burgers is reportedly licensed and legal, therefore no charges have been filed. The range’s director, Sam Scarmardo, shared his reaction to Vacca’s death.

“It’s like losing a brother,” Scarmardo said. “These aren’t employees or associates of ours, these are family. We’re all family.”

Many gun ranges allow children who are 8 years and older –- with parental supervision –- to shoot firearms, Scarmardo said.

He also says that the establishment normally allows children to shoot gun on the range with parental supervision. In other cases, younger children are paired with an instructor.

“We instruct kids as young as 5 on .22 rifles, and they don’t get to handle high firearms, but they’re under the supervision of their parents and of our professional range masters,” Scarmardo said.

Mohave County police sheriff Jim McCabe says the video the parents have of the incident is “gastly.”

‘It’s so easy for us to go back and look at something that’s very tragic and say, ‘Boy! Why did that occur? That should not have happened because of,” said McCabe to Fox News.

Arizona’s gun laws state that a person must be at least 18-year-old to carry a firearm, but the law is null and void when it comes to private properties.
